Abstract: An improved downhole tool apparatus and method for limiting the extrusion of a packer element. The apparatus includes a mandrel having a packer element assembly. Packer retaining shoes are disposed about the mandrel at the ends of the packer element assembly. The packer retaining shoes have an inner retainer and an outer retainer. The inner retainer has a plurality of segments having gaps therebetween that expand in width when the retaining shoe is moved from the initial position in which it is disposed about the mandrel to an expanded position wherein it engages the casing to limit the extrusion of the packer element assembly. The outer shoe is likewise made up of a plurality of segments having gaps therebetween that will expand. The inner shoe segments cover the gaps that exist between the outer shoe segments and the outer shoe segments cover the gaps that exist between the inner shoe segments so that extrusion is limited. The retaining shoes provide enhanced high temperature and higher pressure performance in that extrusion in wells having high temperature and high pressure is severely limited if not completely prevented.

Abstract: L'invention concerne une technique qui permet d'utiliser un ramasse-miettes avec des fonctions de gestion des tas assurées par un allocateur indépendant du ramasse-miettes. Ce dispositif et le ramasse-miettes (139) utilisent une table malloc (319) pour échanger des informations concernant le tas (125). Lorsque l'allocateur détermine qu'il est nécessaire d'avoir un ramasse-miettes, l'allocateur réalise une table de tas dans la table malloc qui spécifie l'emplacement de chaque bloc dans le tas et si ce bloc peut être collecté par le ramasse-miettes. L'allocateur appelle ensuite le ramasse-miettes qui utilise la table de correspondance des tas dans son cycle de marque pour élaborer une liste de marques qui indiquent quels sont les blocs désignés par les pointeurs dans l'espace d'adresses du processeur.

Abstract: Selon cette invention, on soumet un échantillon de pétrole à des radiations électromagnétiques nucléaires au fond d'un puits, et on détermine la masse spécifique et/ou la densité électronique dudit échantillon de pétrole en mesurant l'atténuation des radiations et en l'associant à l'atténuation à la densité électronique. Si les radiations sont des radiations à rayons gamma d'énergie élevée, on considère l'atténuation comme n'étant qu'une fonction de la diffusion de Compton, qui à son tour est liée à la densité électronique de l'échantillon. Si on utilise des rayons X, on mesure l'atténuation, de préférence, dans deux fenêtres d'énergie. A l'aide des deux valeurs d'atténuation différentes établies dans les différentes fenêtres, on peut déterminer l'atténuation provoquée par la diffusion de Compton et l'associer à la masse spécifique et/ou la densité électronique de l'échantillon. En outre, on peut également déterminer l'atténuation engendrée par l'absorption photoélectrique et l'associer à la présence d'au moins un élément lourd (par exemple, le soufre) dans le pétrole et/ou l'ensablement.

Abstract: It is known by the inventor that a synthetic lubricant additive comprising of (a) a polymerized alpha-olefin (PAO), (b) an hydroisomerized high viscosity index hydro-treated severe hydro-cracked base oil (viscosity grade ISO 32), (c) synthetic sulfonate of 300 TBN, (d) a vacuum distilled non-aromatic solvent, and (e) liquefied polytetrafluoroethylene when blended in the proper volumes, the end product can greatly enhance the performance standards of existing lubricants, petroleum based or synthetic, imparts a new and desirable property not originally present in the existing oil or it reinforces a desirable property already possessed in some degree can greatly benefit the consumer. Although additives of many diverse types have been developed to meet special lubrication needs, their principal functions are relatively few in number. This universal synthetic lubricant additive (invention) with micro lubrication technology, when used as directed will reduce the oxidative or thermal degradation of the host oil, substantially reduce the deposition of harmful deposits in lubricated parts, minimize rust and corrosion, control frictional properties, reduce wear, temperature, sludge, varnishes and prevent destructive metal-to-metal contact, reduce fuel consumption and harmful emissions while improving performance through increased horsepower and torque. Further this technology lends itself to further development of a host of energy/emission reduction products from conditioners for kerosene, diesel, bunker-C heavy oils to gasoline, cutting oils, penetrating lubricants, electrical dielectric coatings, oxidation inhibitors and electrical terminal coatings.
